ABSTRACT:
An open-topped box of rectangular horizontal outline, with vertical side and rear walls, has a forwardly slanting front wall terminating at about half the height of the box in a forwardly and downwardly bent handgrip. The handgrip merges at its ends into inner boundaries of two hollow upstanding corner profiles which flank the access opening left above the front wall and have shoulders rising from the bottom to the top of that opening, the lower portions of these shoulders being aligned with two more forwardly positioned ribs of the corner profiles defining with those lower portions a pair of vertical guide grooves for a closure plate insertable from above even when the box is overlain by a similar box to form a stack. The closure plate may be a hinged dust cover of L-profile whose short horizontal leg, resting on the handgrip, projects forward and ends in a pair of gudgeons abutting two webs of lesser height than the ribs also projecting from the corner profiles, the dust cover being provided near its upper edge with lateral wings which are the only parts received in the guide grooves and which can be lifted out of these grooves to let the dust cover pivot forward about its gudgeons into a depending position unblocking the access opening.
